solve the inequality:

-|x-2| + 9 > 6

Answer:

a) 35km

b) 070 degrees

Step-by-step explanation:

To get full marks look at what I did for question (c)

You have to use a protractor on letter s and make sure the 0 on the protractor is facing the letter (N). Now check where 90 degrees is and draw a line straight by using the ruler then use the compass as u can see in the photo, where (x) point is on the end of the compass is your answer {make sure the compass is 2cm which means its 20km. Also make sure to align the compass on the line you drawn}

Thank you

The rule you use is x^(-k) = 1/(x^k)

In this case x = 3 and k = 2, so,

3^(-2) = 1/(3^2) = 1/9

--------------------------------------------

One way to think of it, is to consider the equation below

3^2*3^x = 1

We can solve for x like this

3^2*3^x = 1

3^(2+x) = 1

3^(2+x) = 3^0

2+x = 0 .... the bases are equal, so the exponents must be equal

x = -2

meaning that

3^2*3^x = 1

updates to

3^2*3^(-2) = 1

Now isolate the 3^(-2)

3^2*3^(-2) = 1

3^(-2) = 1/(3^2)

3^(-2) = 1/9

Answer:

Profit shall be distributed as :

First seller = $92

Second seller = $72

Third seller = $36

Step-by-step explanation:

Let the first seller be A

Second seller be B

Third seller be C

Let the profit of third price seller C = "x"

Profit of B = 2x

Profit of A = 2x + $20

Total profit received by all of them = $200

$200 = (2x + $20) + (2x) + (x)

$200 = 5x + $20

$180 = 5x

x = $36

Therefore profit for 3rd seller = $36

Profit for second seller = $36 [tex]\times[/tex] 2 = $72

Profit for first seller = $72 + $20 = $92

Step-by-step explanation:

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]-7(x-3)=x+5[/tex]

Distribute the [tex]-7[/tex] into [tex](x-3)[/tex]:

[tex]-7x+21=x+5[/tex]

Subtract [tex]x[/tex] from both sides of the equation:

[tex]-8x+21=5[/tex]

Subtract [tex]21[/tex] from both sides of the equation:

[tex]-8x=-16[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-8[/tex]:

[tex]x=2[/tex]

_

Check your work by substituting [tex]2[/tex] into the initial equation:

[tex]-7(2-3)=2+5[/tex]

[tex]-14+21=2+5[/tex]

[tex]7=7[/tex]

The answer is correct!

Answer:

x= 120°

Step-by-step explanation:

cos(2x)-cos(x)=0

[tex]\Rightarrow 2\cos^2x-\cosx-1=[/tex]0 [as [tex]\cos(2x)=2\cos^2x-1[/tex]]

[tex]\Rightarrow 2\cos^2x-2\cosx +\cosx-1=0[/tex]

[tex]\Rightarrow 2\cos x(\cos x-1) +(\cos x-1)=0[/tex]

[tex]\Rightarrow (\cos x-1)(2\cos x +1)=0[/tex]

[tex]\Rightarrow \cos x-1=0 \;or\; 2\cos x +1=0[/tex]

[tex]\Rightarrow \cos x=1 \;or\; \cos x =-1/2[/tex]

[tex]\Rightarrow x=\cos^{-1}1 \;or\; x =\cos(-1/2)[/tex]

For [tex]x=\cos^{-1}1[/tex] and 0° < x <180°

There is no possible value of x.

For [tex]x =\cos(-1/2)[/tex] and 0° < x <180°

The possible value of x is

x= 120°

Answer: slopes will be the same!

Step-by-step explanation:

Answer:

In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a line

Step-by-step explanation:

Given that, the total number of students in seventh and eighth grade combined is 584.

The number of students in seventh grade= 5/8 of the total number of students.

[tex]=\frac 5 8 \times 584=365[/tex]

As 4/5 of the total seventh-grade students participated in the track-and-field-event.

So, the number of seventh-grade students participated

[tex]= \frac 4 5 \times 365=292[/tex]

The number of students in the eighth grade 3/8 of the total number of students.

[tex]=\frac 3 8 \times 584=219[/tex]

As 7/8 of the total eighth-grade students participated in the track-and-field-event.

So, the number of seventh-grade students participated

[tex]= \frac78 \times 219=191.625.[/tex]

The number of students must be a counting number, but here, as per the given information, the number of seventh-grade students participated coming out a fractional number, so the given information is incorrect.

Although, as per the given data, the mathematical value of the total number of students participated from both the grade combined

=292+191.625

=483.625 (mathematically)

Again, in real life, the fractional value of the total number of students is not possible.

Given that, the total number of students in seventh and eighth grade combined is 584.

Step-by-step explanation:

Answer:

G = 14 - 1.75(t)

Where G is the number of gallons of gas remaining;

14 represents the amount of gas in gallons in the full gas tank of the vehicle

t is the number of hours

Step-by-step explanation:

Here, we want to write an equation.

We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left

In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons

So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons

Hence, the equation we want to write will be;

G = 14 - 1.75(t)

Answer:

a, b, and c

Step-by-step explanation:

all of them are in the form y=mx+b except for c, which does not have a constant slope throughout the entire line, it will be decreasing or negative until 0, and then increasing or positive after 0, so the slopes would not be the same.
